Being provided with the second pin-and-hole, described bearing pin coordinates with described first pin-and-hole and described second pin-and-hole, with by described power transmission shaft and institute simultaneously
State gear shaft to be fixed together；It is evenly distributed with through hole on the sidewall of described spacer, is inlaid with rotatable in described through hole
Steel ball, one end of described through hole is provided with for described steel ball carries out the spacing conical surface, the riveting of the other end of described through hole
Having for described steel ball carries out spacing conical ring, the diameter of described steel ball is more than the sidewall thickness of described spacer, so that institute
State steel ball and can contact described gear shaft and the inwall of described counterbore simultaneously.
Further, the diameter of described spindle nose is less than the diameter of described gear shaft.
Further, described counterbore is second order stepped hole, and the diameter of the bottom of described counterbore is equal to the internal diameter of described spacer, institute
State the top of counterbore and the diameter at the middle part external diameter equal to described spacer.
This utility model, owing to using technique scheme, is adding man-hour, is processing gear shaft and the laggard luggage of power transmission shaft
Join, both ensure that the physical dimension of gear shaft, in turn ensure that the size for connection of power transmission shaft and ex-ternal transmission parts, make power transmission shaft energy
Enough assembling with ex-ternal transmission parts easily, the most supporting ex-ternal transmission parts also allow for processing；Owing to being provided with
With the spacer of steel ball, the situation that fit clearance at gear shaft and spacer is minimum, drive steel ball to rotate by rotary teeth wheel shaft,
Utilize elasticity and the rotation of steel ball so that gear shaft can slide flexibly and rotate, and prevents gear shaft from blocking, it is ensured that gear
Axle and the assembly precision of power transmission shaft and dimensional accuracy.
